Can Time Be Hacked? Here’s How One Hacker Demonstrated It Can

Posted by in category: cybercrime/malcode

Cher sang about manipulating it while Doctor Who dramatized it. This hacker went one better and did it. Here’s how time got hacked.

During a 1961 address to the National Association of Manufacturers in New York City, John F. Kennedy said that “we must use time as a tool, not as a couch.” Fast forward fifty years, and one hacker has demonstrated exactly how to do that: by hacking time.

What is time anyway? What is time? That’s not an easy question to answer definitively.

A New Camera Can See Through Almost Anything, Including Human Tissue and Bones

Posted by in categories: engineering, space

With the potential to image fast-moving objects.

When asked what superpowers they would like to have, many say the ability to see through things. Now, there may be a camera that could give people that gift.

Developed by Northwestern Engineering researchers, the new high-resolution camera can see around corners and through human skin and even bones. It also has the potential to image fast-moving objects such as speeding cars or even the beating heart.

Happy birthday, ISS.

The first components of the International Space Station (ISS) were launched on November 20, 1998, roughly 12 years after the first Soviet MIR-2 module was launched and a full 25 years after Skylab.

SpaceX Embarrassed NASA With Their High Tech SpaceSuit: Whether it’s science fiction or science fact with space as the backdrop, there is one thing that always catches the eye; the spacesuit. Indeed, we’re all familiar with the sense of excitement and inspiration when we see astronauts decked out in advanced spacesuits.

SpaceX being who they are has dropped a bomb in the form of a new spacesuit design, and it’s nothing like what NASA has ever done. What makes this advanced space suit so unique, that it’s obliterating what NASA has ever done? Join us as we explore every detail of the spacesuit.

NASA seeks ideas for a nuclear reactor on the moon

Posted by in categories: government, nuclear energy, space travel

If anyone has a good idea on how to put a nuclear fission power plant on the moon, the U.S. government wants to hear about it.

NASA and the nation’s top federal nuclear research lab on Friday put out a request for proposals for a surface power system.

NASA is collaborating with the U.S. Department of Energy’s Idaho National Laboratory to establish a sun-independent power source for missions to the by the end of the decade.

Alphabet is putting its prototype robots to work cleaning up around Google’s offices

Posted by in categories: employment, robotics/AI

They’re a long way from taking human jobs.


Alphabet says its Everyday Robot team at X is now testing its prototype machines in Google’s offices. The bots are performing light custodial work as Alphabet slowly pursues its goal of building a “general-purpose learning robot.”

MediaTek Aims to Beat Qualcomm With New Flagship Smartphone Chip

Posted by in categories: computing, mobile phones

The Dimensity 9,000 is both the first smartphone chip to be built using TSMC’s new 4nm process and the first chip to feature Arm’s new Cortex-X2 CPU core. The flagship chip is based on the new ArmV9 architecture and will feature the Cortex X2 as an “ultra” performance core, three Cortex-A710 cores as general “super” performance cores, and four Cortex-A510 efficiency cores. The Dimensity 9,000 will support LPDDR5x memory at bandwidths of up to 7,500 Mbps.

The big jumps in performance don’t stop there: The Dimensity 9,000 is also the first chip to feature Arm’s Mali G710-MC10 GPU, along with industry-leading support for raytracing via the Vulkan SDK for Android. And while there aren’t any phones currently available that have pushed refresh rates this high, MediaTek claims the Dimensity 9,000 can handle screens with up to a 180Hz refresh rate at FHD+ resolutions.

The Dimensity 9,000 also supports the first 18-bit image signal processor, which gives the chip the ability to capture 4K HDR video using up to three cameras at the same time, or still photos using up to a massive 320-MP sensor (assuming device makers can find a 320-MP sensor that fits in a phone).

Sustainable electrochemical process could revolutionize lithium-ion battery recycling

Posted by in categories: chemistry, sustainability

Spent lithium-ion batteries contain valuable metals that are difficult to separate from each other for recycling purposes. Used batteries present a sustainable source of these metals, especially cobalt and nickel, but the current methods used for their separation have environmental and efficiency drawbacks. A new technology uses electrochemistry to efficiently separate and recover the metals, making spent batteries a highly sustainable secondary source of cobalt and nickel—the reserves of which are currently dwindling.

A new study, led by University of Illinois Urbana-Champaign chemical and biomolecular engineering professor Xiao Su, uses selective electrodeposition to recover valuable metals from commercially sourced lithium manganese oxide—or NMC—battery electrodes. The method, published in the journal Nature Communications, produces final product purities of approximately 96.4% and 94.1% for cobalt and nickel, respectively, from spent NMC wastes.

Su said cobalt and nickel have similar electrochemical properties—or standard reduction potentials—making it challenging for chemists to recover pure forms of each metal from battery electrodes.
